Multiple languages
Note: This trick is dependent on which version of the Neo*Geo Pocket you have. Start up your Neo*Geo Pocket without a cartridge. When the main menu appears, select "Settings", then choose another language to run a gam in. For example, if you have a North American Neo*Geo Pocket system, there are two language choices (English and Japanese). Select Japanese as your language, then turn off your Neo*Geo Pocket after leaving the settings option. Insert a game cartridge, and you can now play in that language. All Neo*Geo Pocket games support multiple languages, allowing games bought from any region to be played in any version of the system.
